Results: :
With a mean follow–up period of 10 months (range;2–21), 10 of 13 eyes that had COMET for corneal surfacereconstruction achieved stable ocular surface. In these eyes,fibrosis and vascularization were markedly regressed althoughvisual acuity was not significantly improved. Three of theseeyes that had secondary keratoplasty showed clear grafts andsignificant improvements in visual acuity. Histological examinationrevealed that the corneal surface was covered by multi–layeredepithelial cells that were negative for keratin 3 and faintstaining for keratin 13. Nine of 11 eyes achieved deep fornixor lysis of symblepharon. As complications, 2 eyes had persistentepithelial defects, 2 had recurrence of symblepharon, 3 hadpostoperative glaucoma, and one had corneal perforation. Noinfection or immunological rejection was noted.

Conclusions: :
COMET seems to be a useful alternative for reconstructionof bilateral ocular surface disorders. Since stable ocular surfacestatus can be obtained in many cases following COMET, subsequentkeratoplasty may be useful for visual recovery.
